NuTAP-S61 is a portable network TAP device. Embedded with 2 Network Ports and 2 Monitor Ports, NuTAP-S61 can monitor and redirect any data streams which flowing through it. Moreover, NuTAP-S61's Console Port allows users to access test data and configure test variables while serving as an optional power source for NuTAP-S61. Network TAP is a hardware device which allows monitoring data flows in a network environment dynamically without any interference. As mentioned above, NuTAP-S61 is embedded with two Network Ports and is capable of monitoring all data flows between two network points. All data traffic flows between NuTAP-S61's Network Port A0 and A1 can be brought out for further analysis and research dynamically and without intervening network environment. NuTAP-S61 is a compact, lightweight, and highly cost-effective device that provides 3 different filters for users to choose: Forwarding Filter, Re-Direct Filter, and Capture Criteria. All these filters are powered by Xtramus SDFR (Self-Discover Filtering Rules), which makes packet capturing/filtering over Ethernet easy and convenient.

● Portable and light-weighted, with high-performance and reliable test results 
● Filter and redirect TAP streams to monitor port by SDFR technique which can ease the loading of monitor PC Xtramus Technologies 1 Product Brief｜NuTAP-S61
● SDFR (Self-Discover Filtering Rules), a set of filtering rules including Destination Address, Source Address, VLAN, Destination IP, Source IP, Destination Port, and Source Port 
● 2 Network Ports and 2 Monitor Ports of 10/100 Mbps UTP Ethernet port 
● 1 Console Port which allows users configuring test variables, accessing test results, upgrading firmware/FPGA, and serving as NuTAP-S61's optional power source while connected to PC with a RJ45-to-USB cable* 
● Both Network Ports support Universal Stream Counter (USC), each USC can contain up to 256 sets of 32-bit statistics including Packets, Bytes, Packet Broadcast, CRC Error, IPCS Error, Packet Multicast, and Transferring Rate.

● NuSet-MiniTAP is a utility software designed for NuTAP-S61 and runs under Windows® environment. When connecting NuTAP-S61 with your PC via a Mini USB cable, it allows users to: 
   - Upgrading NuTAP-S61's firmware and FPGA 
   - Monitoring data flows in the network environment 
   - Configuring test settings and accessing test results
